8-Stage Static Bidirectional Parallel/
Serial Input/Output Bus Register

High-Voltage Silicon-Gate CMOS

The SL4034B is a static eight-stage parallel-or serial-input parallel-

output register. It can be used to:

1) bidirectionally transfer parallel information between two buses, 2)
convert serial data to parallel form and direct the parallel data to either
of two buses, 3) store (recirculate) parallel data, or 4) accept parallel
data from either of two buses and convert that data to serial form.
Inputs that control the operations include a single -phase CLOCK (CL),
A DATA ENABLE (AE), ASYNCHRONOUS/SYNCHRONOUS (A/S),
A-BUS-TO-B-BUS/ B-BUS-TO-A-BUS (A/B), and PARALLEL/SERIAL
(P/S).

Data inputs include 16 bidirectional parallel data lines of which the
eight A data lines are inputs (3-state outputs) and the B data lines are
outputs (inputs) dependung on the signal level on the A/B input. In
addition, an input for SERIAL DATA is also provided.

All register stages are D-type master-slave flip-flops with
separate master and slave clock inputs generated internally to allow
synchronous or asynchronous data transfer from master to slave.

• Operating Voltage Range: 3.0 to 18 V

• Maximum input current of 1 µA at 18 V over full package-

temperature range; 100 nA at 18 V and 25°C

• Noise margin (over full package temperature range):

1.0 V min @ 5.0 V supply

2.0 V min @ 10.0 V supply

2.5 V min @ 15.0 V supply

This device contains protection circuitry to guard against damage due to high static voltages or electric
fields. However, precautions must be taken to avoid applications of any voltage higher than maximum rated
voltages to this high-impedance circuit. For proper operation, VIN and V

OUT

should be constrained to the range

GND≤(VIN or V

OUT

)≤VCC.

Unused inputs must always be tied to an appropriate logic voltage level (e.g., either GND or VCC).
Unused outputs must be left open.
